ROLLER-SKATE.

SPECIFICATION forming part of Letters Patent No. 237,152, dated February1, 1881.

Application tiled May 17, 1880. (No model).

To all whom it may concern:

Be it known that I, ALANsoN Woon, of the city of Toledo, in the countyof Lucas and State of Ohio, have invented certain new and usefulImprovements in Boller Skates; and I do hereby declare that thefollowing is a full, clear, and exact description of the invention,which will enable others skilled in the art to which it appertains tomake and use the same, reference being had to the accompanying drawings,and to letters of reference marked thereon, which form a part of thisspecification.

My invention has relation to that class of roller-skates which have fortheir object to provide means for increasing and diminishing the lengthof the skate, so as to readily adapt the same to different-sized feet 5and it consists in forming the frame of the skate out of twosemicylindrical tubes, which are adapted to slide upon each other andprojecting into cylindrical sleeves or recesses at'each end of theskate, and clamped therein by suitable set-screws at proper distancesapart.

It further consists of the compensating axlejournals at each end of theskate, all as will be hereinafter more fully described, and pointed outin the claims.

In the drawings, Figure 1 is a top-plan view of my invention; `Fig. 2, arear elevation, and Fig. 3 a detail sectional view of the axle-frame.

Similar letters of reference indicate like parts in the several figures.

Referring to the drawings, A A represent the toe and heel plates of theskate, which are secured to the top of the hollow cylindrical frame B ateach end, a semi-cylindrical tube, O, projecting from the inner end ofeach of the frames B, to which they are rigidly attached, so as to formpart thereof, and the free ends of which lap past each other and slideinto the cylindrical sleeves or frames B, opposite each other, as shown.

To one side of the frames B are arranged setscrews D, which are` adaptedto be clamped upon the semi-cylindrical tubes C, so as to hold themrigidly at the desired distances.

To the front of the forward frame B, and at the rear of the rear frameB, is formed acurvilinear frame, E, which is adapted to receive theaxle-frame F, as shown in Fig. 3. The frame E is provided with a seriesof openings, a, on each side, and the axle-frame F is provided with acentral opening, b, to permit of the entrance of the square-headed boltG, which passes through the openings c b, to secure the axle-frame Fwithin 'the frame E, a block of rubber or other elastic material, H,being interposed between the axle-frame and the frame E, as shown inFig. 3.

The construction of my invention being as described, it will be observedthat in the operation of the same, by looseningtheset-screws D the skatemay be lengthened or shortened to suit different-sized feet, and can beheld at suitable distances apart by tightening the setscrews.

It will also be observed that the bolt Gr can be introduced through thevarious openings a of the frame E and through the opening b of theaxle-frame F, so as to give either a loose or tight bearing to theaxle-frame.

Having thus described my invention, what I claim as new and usefulis- 1. In a roller-skate, the frames B B, having semi-cylindrical tubesC attached thereto, and provided with the heel and toe plates A, andbearing-frame E, adapted to receive the axleframe F and rubber block H,secured thereto, substantially as and for the purpose specified.

2. In a roller-skate, the combination of the axle-frame F, havingcentral opening, b, with the frame E, having openings a, and bolt Gr,and provided with rubber block H, substantially as and for the purposespecified.

In testimony that I claim the foregoing as my own I have affixed mysignature in presence of two Witnesses.

ALANSON WOOD.
